TELEPHONE TOLL DEVICE AND CIRCUITS THEREFOR.

Patented Nov. 17. 1914.

Application filed October 12, 1912. Serial No. 725,491.

To all whom it may concern Be it known that 1, James L. MGQUARRIE, a citizen of the United States, residing at Montclair, in the county of Essex and State ofNew Jersey, have invented a certain new and useful Improvement in Telephone Toll Devices and Circuits Therefor, of which the following is a full clear, concise, and eXact description.

This invention relates to telephone toll apparatus and systems and more particularly to mechanism and a circuit therefor for charging the number of successful calls originated by a telephone subscriber although not exclusively limited to such use.

One object of this invention is to provide an improved and reliable toll device and toll line system for charging the number of successful calls.

Another object is to provide means which may be operated to automatically produce a distinctive warning signal for the operator or the subscriber, or for both.

This invention will *be fully understood from the following description taken in connection with the accompanying drawings in which,

Figure 1 is a perspective view. of the mechanism assembled, with certain parts broken away to more clearly exhibit the method of its operation; Fig. 2 is a perspective view with the working parts separated to clearly show their relationyFig. 3 is a side elevation with the inclosing case and a part of the base and supporting frame in section; Fig. l is a top plan view with the inclosing' case removed and the micrometer device in section; Figs. 5 6, 7, 8 and 9 are detailed views of the construction shown in side elevation; Figs. 10 and ll are plan de-;

therein.

The base 5 furnishes the support for the registering and signaling mechanism and the inclosing cover 6. A registering train comprising numbered wheels 7 8, 9 and 10 is supported on a shaft 11, having bearings imparted to'the wheels 9 8 and 7 by well known means so that the count may be registered in units, tens, hundreds and thousands. A ratchet wheel 13 rigidly secured to the wheel 10 to impart motion thereto is likewise carried on the shaft 11. At the end opposite the ratchet wheel 13, and preferably outside of the frame member 12, the shaft 11 carries a micrometer device comprising an inner threaded tubular portion 14:, and an outer threaded tubular portion 15. The inner portion 1 1 is formed integral withan outer cap or barrel 16, which is provided with slots 17 'at intervals about its circumference for a purpose to be hereafter described. Graduations are likewise provided on the circumference in the form of numerals to assist in setting the mechanism for a predetermined number of calls. The inner tubular portion besides having screw threads on its outer surface adapted to mesh with screw threads on theinner surface of the outer tubular portion 15, has an axial hole therethroughthreaded to receive a split screw 18 whose function is to-correct the zero reading of the micrometer in a way well known in the art. The outer tubular portion l5'is rigidly attached to the shaft 11 so as to rotatetherewith.

Mechanism for rotating the register train provided, theinitial movement of which is produced by a subscriber when originatlng a call. Extending upward from the base 5 are posts and'26 each forming a support and bearing for a rotatable shaft 27. The shaft 2? has a lever 28 which-projects through a suitable opening in thecover where it-may be manipulated by a subscriber to turn the shaft 27 in the direction of the arrow shown in Fig. Loosely mounted on the shaft '27 within the cover is an upwardly projecting lever 29 provided with a pin 30, and a spring '31 securedto said lever and to the frame. A lever 32 rigidly secured to the shaft 27 to be turned thereby engages the pin when rotated, thereby imparting motion to the upwardly projecting lever 29 against the tensionqof the spring 31. At its upper end the lever 29 carriesa stepping pawl v33 pivoted thereto by a pin 34. It will therefore be understood that when the shaft 27 is rotated in the direction of the arrow by lever. 28 the pawl 33 is advanced into op erative position relative to the ratchet wheel 13. A- downwardly projecting lug 35 of the frame member 12 carries a stop lever 36 pivoted. thereto at 37. A spring 38 secured to the lug and to the lever 36 tends to keep the free end thereof elevated so that the lever takes, approximately, a horizontal on u l g. otherwise displaced as hered5. The rearwardly projecting end 39 ot' the pawl 33 is provided with a shoulder ll) which may be engaged by a laterally proj-ec ing lug ll of the lever 36 when the pawl has been advanced by the rota; tion of lever through the agency of shaft 27 and levers 352 and as hereinbolore described. "the pawl 33 is thereupon held in its advanced pi'isition until released to ro tate the rister train as hereinafter deshoulder 42 of the pawl 33 is ngage the edge of a hole in the through which the registering i is project to limit the return movement of the pawl. A. holding pawl 4L3 positioned to engage the teeth of the ratchet wheel 13 to prevent the same from being rotated by the pawl dragging over the teeth thereof during its forward movement.

in rotating the lever 23 to advance the pawl irto operative position relative to the regi train, as hereinbefore described, means ar also made operable whereby a sig nal may be communicated to the central office to no iv the operator that a connection is desired. A third post projecting upwardly from the base 5 provides a pivoted connection 51 having an upwardly projecting cam-shaped lever A bell crank shaped holding pawl 53 pivotally supported on the lever 52 at 54 and is provided with a dowi'iwardly and laterally projecting lug i l. caring 56 secured at one end to the lug and at the other end to the frame subjects the lever to lateral and the free end of the holding pawl 53 to downward pressure. A hook 57 on the free end of the holding pawl 53 normally engages a latch 58 on the trame member 12 as shown in Fig. 3. lVhen the lever 28, however, is rotated, a pin on the lever 32 engages the pawl raising the free end thereof about the pivot 54: against t 1 tension of the spring 56 until the hook 534 disengaged from the latch 58 as shown by the dotted lines in Fig. 9. The unlocking oi" the pawl 53 allows the spring 56 to rotate the lever 52 about its pivot 51. A pin. 60 carried by the upper end of the lever is positioned to engage a contact spring 31 when the lever 52 is displaced by the spring 56, thereby causing the spring 61 to make contact with a second spring 62, as shown by the dotted lines in Fig. 9 completing the signal circuit.

Two uprights and 71 secured to the base 5 support and provide bearings for a shaft 7 2 on which an inertia wheel 73 is se curely mounted. The wheel 73 is preferably made comparatively heavy so as to be able to exhibit considerable inertia when rapidly displaced. A lever 7d rigidly attached to the shaft 27 is provided with a projecting pin 75 adapted when moved to engage a rib on one of the spokes of the wheel 73, impart ing a rotary motion thereto. A spring 7 3 engaging the lever 74 serves to return said lever and the shalt 27 to normal position when the lever 28 is released. A coil spring 77 secured at one end to a lug 78, fastened to the upright 7i, and at the other end to the shaft 72 serves to return the wheel 73 to its normal position when the same has been displaced, by a subscriber turning the lever .28 and released by the operator as hereafter described. The shaft 27 is likewise provided with a lever 79 rigidly mounted thereon, adapted to engage a bell crank lever 80 piwtally supported on the tonight 71 at 81. A spring 82 secured to the lever 80 and to the frame subjects said lever to tension tending to cause it to resume its normal position as shown in Fig. 7 when displaced y the lever 29 through the agency of the lever 28. pin 83 carried by the lever 80 is positioned to engage a notch. 84- in the rim of the wheel 73 to lock said wheel in its advanced position. lhe contact between the pin 83 and the notch 8d likewise holds the lever 80 in an elevated position shown in Fig. 6. A second bell crank lever 35 pivoted. to "the lever 80 at 86 serves to unlock the wheel 73 by lowering the lever 80 until the engagement between pin 83 and notch St is broken. The unlocking action of lever is under the control oil? the central o'llice operator as hereinafter described. The post 87 projecting upward from the base and to which one end of the spring 32 is secured serves to hold the free end of the lever 85 elevated.

The wheel 73 provided with an insulated lug 90 adapted to engage a contact spring 91, which spring when so engaged, contacts with second spring 92. However, when the spring 91 is not engaged by the lug 90 under the pressure off the coiled spring 77. said spring scpaJ- itself from the spring 92 as shown in rigs. l and (l. ll hen the wheel 73 is released through the agency of lever 30 the energy stored up in the spring 77 by its displacement, causes said wheel to rotate about its axis; the lug 90 strikes the spring 91 and the tension of the coiled spring 77 and the inertia of the wheel 73 momentarily overcome its resili oncy, causing said to contact with spring lhe ener stored up in the springs 91 and 92 during this movement is suthcient to overcome the force of: the coiled spring '77 and the inertia of the wheel 73, forcing said wheel to rotate in the opposite direction until the lug 9O disengages with spring The contact between springs 91 v however, ineffective until a predetermined number of calls has been exhausted.

' Means are provided. whereby the advancement of the register train and the release of the above described signal wheel are under the control of the central oiiice operator. An electromagnet comprising the coils 93 is secured to the base 5 and is provided with an armature ea pivot-ed at 95. The armature 9-1 is maintained in anormal or neutral positionrelative to the poles. of the coils 93 by the action of springs and levers in a manner well known in the art,'but is adapted to be rotated about its axis in either direction, depending upon the direction of the flow of current through the energizing coils. When rotated in a clockwise direction, as shown in Fig. 7 j the armature 94L strikes the end of the bell crank lever 85, if the wheel 73 and the lever 80 have been displaced by theaction of lever 28, thereby releasing the wheel 73 by lowering the lever 80 until the pin 83 and the notch 84 in the said wheel are disengaged. If the armature is turned in the other directionno such action occurs. Secured to the armature 94 in the plane of its pivotal axis is a lever 96 provided with an upwardly projecting arm 97.

. the upright arm 97 at 98 and adapted to be moved thereby is a lever 99 with a camshaped projection 100 at its free end. The cam-shaped projection 100 is adapted when moved to the right by the armature to disengage the holding pawl 36 from the shoulder 10 of the stepping pawl 33, allowing the latter to actuate the ratchet wheel 13 of the counting train. If, however, the armature is rotated in the opposite direction, the lug 100 does not engage the holding pawl 36 and thetrain is not advanced.

In order to return the mechanism to its normal position and to open the signal circuit at the-contact springs 61 and 62' to in Pivoted to hook .57 is beyond the latch 58 as shown in Figs. 8 and 9. The return of the armature to normal position allows the spring 56 to actuate the lever .53 until the hook 57 and the latch '58 are in engagement. An insulated pin 111 projecting from the center of the wheel normally rests in a groove'l12 of a cam 113, secured tothe spring 61.. When. the armature is tilted, the pin rides out of the groove upon the cam on either side thereof, depending upon the direction of movement of the armature, and causes the spring 61 to continue its contact with the spring 62. for 'a short interval. The energizing circuit is therefore not broken until the'posit'ive operation ofthe mechanism is insured. Later in the movement of the. armature, however, an insulated pin 115 carried by the lever 99 engages an offset 116 on the spring 62, thus separating prings 61 and 62 to open the circuit.

The micrometer device hereinbefore described controls the operation of the warning signal through the agency of mechanism actuated thereby. Pivoted to the frame member 12 at 1.20 is a lever112-1 under the tension of a spring 122. On one side of its pivot 120 the lever 121 is provided with an offset 123 adapted to engage the notches 17 in the barrel 16 of the micrometer device. 'At the other end the lever 121 is provided with a catch 121-.v A target 125 is carried on a pivot 126 having a bearing in and projecting through the frame member 12.- The pivot 126 carries an arm 127 provided with a notch 128 adapted to be engaged by the catch 12 1- 'as shown in Fig. 11 when the offset 123 is in one of the notches 17. This engagement may however. be broken when the oifset 123 rides out of a slot 17 upon the outer circumference of the barrel 16. A coiled spring 129 is secured at one endto the arm 127 and at the other end to the frame so that whenthe said target is locked in the position shown in Fig. 11 it is under tension. When the catch 121 releases the arm 127 the target 125 is rotated together with its axis, by the tension of the spring 129 in the direction shown by the arrow in Fig. 11. A pin 130 carried by the target 125; is in a position to strike the lever 131' pivoted to the frame at 132 when the target is thus rotated. An insulated lug 133 carried by the lever 131 is adapted to engage. a contact spring 134 when the saidlever is struck by the pin 130 carried by the target. The contact spring 134 is thereupon forced to contact with'a spring 135 which, together with the said spring 134, is adapted to close a branch circuit includingthe springs 91'and 92, causing the intermittent making and breaking of the circuit thereat to become effected.

At a substation A are located the usual speech receiving and transmitting means, a

switch hook and signaling device together with the mechanism peculiar to this invention. The line circuit 136 extending from the substation A to the central oilice B is connected by conductors 137 and 138 to a resistance 139 which is adapted to compensate tor the resistance of the coils 93 when they are removed from the line; and the resistance 139 connected to contact spring 91 by conductor 140. Conductors 137 and 1111 join the line circuit 136 to the coils 93. The contact spring 62 is connected to the opposite terminal of the coils 93 by conductor 11-2. Contact springs 61 and 135 are connected together by condi'ictor 1 13 and to ground by conductor .111 while the contact springs 92 and 13. are joined by a conductor 1-15. lt will thus be apparent from an examination or Fig. 12 that the closing of the contact between springs 61 and 62 or the contacts between. springs 91 and 9'2, 131 and 135, will close circuits to the central otlice, the former including the coils 93 and the latter the resistance 139.

In, order to limit the movement of the wheel caused by the turning of the lever 28 as hereinbei'ore described, a stop 116 is positioned to engage the pin carried thereby.

The two halves of the target are preterably given a different color as shown by the shaded and unshaded portions in the \arious figures. ll hen the target is turned to be locked by the catch 121, the unshaded portion is visible to the subscriber through a window 137 in the cover 6. Upon being released. however, the target is rotated by the spring 129 until the shaded portion appears beneath said window, notifying the subscriber that the predetermined number oi calls has been exhausted. A. window 138 in the cover 6 allows the counting wheels to be seen without removing the cover.

At the central oflice 13 the line 136 terminates at the tip contact of the usual spring jack 1.530, with a branch conductor 1.51 extending to a back contact 152 of a relay 153. An armature 1.51 of relay 153 is connected by conductor 155 to a relay 156 and thence by conductor 157 to grounded battery 158. The relay 156 controls the signal lamp 159 through its armature 160, conductors 161, 163 and 161 and grounded battery 165. The sleeve contact of the spring jack 150 is connected to ground through conductor 166 and the coil of relay 153. The usual plug 170 has its sleeve contact connected by conductor 171 to a grounded battery 17 2 while the tip thereof is joined by conductor 173 to two keys 17 1 and 175. The key 17-1 has its contact point connected by conductor 176 to a relay 177 and thence by conductor 178 to a grounded source of positive current 179. Key has its contact point connected by conductor 180 to relay 181 and thence by conductor 182 to a- Q'rounded source of negative current 183. Armatures and 191 01 relays 177 and 131 respectively are grounded. The relay 177 is provided with a normally open front contact 192 connected by conductors 193 and 19 1 to a signal lamp 195 and thence by conductor 196 to grounded battery 197. Relay 181 is likewise provided with a normally open front contact 195 which is connected to lamp 195 by conductors 199 and 191. It will thus be readily apparent that when either of keys 171 or 175 are depressed to send current orer the line the signal lamp 195 is lighted notifying the operator that the ci'lrrent is t'lowing'.

The zuiparatus is set for a predetermined number of calls by rotating); the barrel 16 until the otl set rests in a groove 17, representing the number of calls desired. The target 125 is rotated against the tension of s n-ins; 129 until the catch 1.2 1 carried by the lever 1: .1 engages the notch 138 in the lever The unshaded portion of the target s thereupon.Yisible through the window Desiring to inalize a call, the subscriber turns the lever 23 with its shaft .27 as far as possible in the direction shown by the arrow in and releases the said lever. This movement of the shaft 27 causes three things to take place within the mechanism; the contact between springs 61 and 62 is closed through the agency of pin 59 carried by lever 32, unlocking the lever and the spring 56 retractingthe said lever as hereinbei'ore described. A circuit is completed from ground at the substation conductor 11-1, contact springs 61 and 62, conductor 1 12, coils 93, condi'ictors, 14-1, 137, 136 and 151, back contact 152, armature 1.531, conductor 1.55, coil or relay 156, conductor 157 to grounded battery The relay 156 pulls up its armature and the operator is thus notified that a connection is desired by the lighting of lamp 159 over a circuit from grounded battery 165, conductor 164, lamp 159. conductor 163, armature 160 and conductor 161 to ground. The stepping pawl 33 advanced into operative position rel-a.- tire to the ratchet wheel 13 by the lever 29, to be there held by the offset 1-1 of the hold ingr pawl 36 engaging the shoulder 1-0; and the inertia wheel 73 is moved against the pressure of snrin 77 h the lever 74' until- 1 1 1 the pin 99 contacts with the stop 116 in which position it held by the engagement of pin 63 carried by the le er 30 and the. notch 3-1. The coils are however not one rized sutliciently to attract their armature 9'!- since their resistance is sulliciently high to prevent the passage of operating current therethrough at the Voltage of battery 158. The insertion of plug" 170 into spring jack 150 energizes relay 153 through i a circuit from groundedbattery 172, conductor 171, sleeve of plug 170, sleeve contact of spring jack 150, conductor 166, relay 153 to ground. The armature 154 is actuated, separating itself from the back contact 152, breaking the energizing circuit for relay 156, and causing the lamp 159 to be extinguished. If the call. is successful the operator depresses one of the keys, for example key 171', completing a circuit from the grounded source of positive current 17 9, conductor 178, relay 177, conductor 176, key 174, conductor 173, tip of plug 170, tip contact of jack 150, conductors 136, 137 and 141, coils 93, conductor 1412, contact springs62 and-61,

and conductor 11% to ground. The coils 93 are thus energized in such a direction thatthe armature 91 is turned in a clockwise direction and the lamp 195 is lighted over a circuit from grounded battery 197, conductor- 196, lamp 195, conductors 194: and 193, contact 192, armature 190 to ground. The operator is thus notified that a call is being registered. The pawl'33 is thereupon re.- leased by the lever 99 to actuate the counting train one step, and the wheel 73 is released by the lever to intermittently close the contact between springs .91 and 92 as hereinbefore described. rThe lever 53 is, atthe same time, advanced by the roller "and locked. in normal position by the latch-58 andthecircuit is-opened at springs .61 and 62 by the pin carried bythe lever .99, denergizing relay 177 and notifying the operator that the registration is completed by the extinguishment of lamp 195. ,The

intermittent opening and closing'of'cont'act 9192 continues after the opening of contact til-62. ed for each successful call; The outertubular portion 15 of the micrometer device is turned step by step as the successful calls are registered while the barrel 16 and'the inner tubular portion 14 are prevented from so rotating by the action of the offset 123 of the lever 121 being in engagement with one ofthenotches 17. When the predetermined number of calls is exhausted, the inner end of the screw 18 carried by the inner tubularportion 14 engages the end of the outer tubular portion 15 and the ad.- vancement of the train rotates the barrel 16. The offset 123 of lever 121 is thereupon forced to ride out of the notch 17, in which it has been resting, releasing the target 125 so that the shaded portion thereof is visible beneath the window 137 warning the sub scriber; and the lever 131 closes the contact between springs 13% and 135. .The opening and closing of the contact :between springs 91 and 92 is thereupon made effective after the opening of contact 61'62 as hereinbefore described and when the next call is registered by the depression of key 174E a flashing signal "is provided for the The above operation is 'repeatoperator by .means of the following circuit 1 ground at the substation, conductors 1-1-1 and 113, contact springs 135 and 13 1, conductor. 1 15, contact springs 92 and 91, conductor 110, resistance 139, conductors 138, 137 and being completed from groundedsource of negative current. 183, conductor 182, -relay 181, conductor 180, key 175, conductor 173, tip of plug 170, tip conta'ctbfjack 150, conductors 136, 137 and 141, coils93, con.- ductor 142, contact springs 62 and 61, conductor 144 to ground. VVhe'n the armature 94: is thus turned, the stepping pawl 33 and the wheel 73 are not released for reasons hereinbefore given, the only eiiect being that the circuit is opened at springs 61 and 62 and that relay 181 attracts its armature 1 91. The stepping pawl 33 and the inertia wheel 73 are therefore held in their advanced positions regardless of the further actuation of the lever 28 until the next. suc cessful'call. The operator isnotified that a calliis not being registered by the light grounded battery 197, conductor 196, lamp 195, conductors 194; and 199, front contact 198,armature191 to ground' The opening of contact 6162 eXtin'guishes the lamp 195 by opening the energizing circuit for relay What I claim is; '1.
